MTest Pixel Telescope – Status Update David Christian September 11, 2007

MTest Telescope Constructed using “BTeV pixels” Pixel size = 50  x 400  (600  ) Oriented to provide “precision-x” or “precision-y” measurements.

Layout Aperture ~ 3.5cm x 3.5cm 4 – 6 stations Beam x y x y

Nomenclature Station = 2 planes & an SLINK Plane = 3 modules mounted on a TPG heat spreader Module = hybrid pixel detector glued & wire-bonded to a High Density Interconnect (Kapton flex circuit) Hybrid = pixel sensor bump bonded to 4 FPIX2.1 ASICs

DAQ Overview SLINK ROUTER Twin-ax (sATA) PCI Interface Fiber Trigger/timing signals LINUX pc Removable disk

DAQ SLINK communicates with 2x3x4=24 FPIX2.1 chips & with ROUTER. –Relays commands & responses –Collects data Deserialize (digital phase follower) Time order & construct data blocks w/extended time stamp & chip ID headers Hierarchy of 2-way data merges

DAQ - continued ROUTER communicates with PCI interface & SLINKs and (optionally) DUTs –12 sATA ports, 4 RJ45 ports –Relays commands & responses –Collects data Hierarchy of 2-way data merges (same logic as SLINK) PCI Interface communicates with ROUTER & pc –Relays commands & responses –Uses 3 CSRs & 3 ring buffers in the pc main memory (64 MB)

Detector Status/Plan Hybrid development complete –11 good hybrids in hand –Balance waiting for LANL PO to VTT Delivery Jan – May (schedule risk) Module development –4x HDI layout ~85% complete (FNAL) –Prototype by end of October, production Nov- Dec (on the optimistic critical path)

Detector Status/Plan continued Plane/Station development: –TPG in hand, reinforcing about to start (FNAL) –Mechanical design underway (FNAL) –SLINK pcb layout & final design is waiting for completion of 4x HDI (Nevis) Box/Area: –Cleanup has started –Mechanical design underway (FNAL)

DAQ Status/Plan DAQ Hardware/Firmware (Nevis) –PCI interface ~90% complete (trigger/timing hooks not written) –Router ~70% complete (trigger/timing, implementation of merges, integration of DUT?) –SLINK Prototype tested at ~90% level; linked to 2 modules Design/layout waiting for 4x HDI On the optimistic critical path

Software Status/Plan Online software (FNAL, Syracuse?, UNM?) –Core low level routines exist & have been tested. –Need to specify online, including online/offline boundary, write & test code. On the optimistic critical path Offline software (Syracuse, FNAL?, UNM?) –Data unpacking –Alignment –Tracking, integration of DUT On the optimistic critical path Strategic decisions to be made in the next 4-6 weeks

Schedule Focus on full telescope in ~Feb If bump bonding is delayed (past ~Jan)… –Install 1 st station + fragments as available (~Jan?)
